Can a VHS VCR record single video frames at a time?
It would be nice if it were possible to output still frames from a PC, for example, to record computer animation on video tape. This would permit images to be generated slowly and then played back in real-time. However, there are a couple of problems with attempting to cleaning record single frames on a consumer grade VCR: • Without moving the tape, only a single field (of the two interlaced fields in a video frame) can be recorded since the tracks for the A and B heads will be superimposed. I doubt that any VCR not specifically designed for single frame recording has any support for moving the tape in this manner. • The control and synchronization circuitry to cleanly switch the record for a single frame may not exist. This will depend on the model – the more sophisticated the editing functions that are supported, the more likely that this precision will be supported. • The VCR must have a flying erase head or you must use new or pre-erased tapes to avoid the rainbow interference on t
